13.3 Servicing - Internal Integrity
Safety Note: Before removing the front cover; the correct
shut down sequence must be followed for your own safety.
Before servicing, ensure that the boiler is cool with the
engine head below 120°C – otherwise there is a risk of
electric shock even with the supplies disconnected. The head
temperature may be accessed via the THINK Controller.
Press the MENU Button. Turn the Selector Button to highlight
‘Information’. Press the Button to select. Turn Selector Button
until ‘head temp actual value’ is shown.
Ensure that both the gas and electrical supplies to the
appliance are isolated - wait a minimum of 6 minutes 30
seconds before any work is started - again there is a risk of
electric shock even with the supplies disconnected.
NOTE: Before undertaking any service work that entails the
removal and replacement of parts, ensure that the center
transit bracket is refitted to protect the engine head (see
Fig.48). This bracket must then be removed before running
the engine.
1. Remove the plastic facia on the front of the appliance which is
held on by two magnets (Fig. 51).
2. Remove the two screws and the front case by pulling forward
at the bottom edge and then lifting clear of the engagement at the
top of the appliance (Fig. 51).
3. Undo the four screws from the bottom cover and remove the
cover (Fig. 51).
4. Remove the two screws on the front of the control tray to gain
access to the control tray area (Fig. 52).
5. Inspect the unit for any signs of water damage and rectify any
leaks.
6. Generally check the conditions of the wiring of the appliance
and the external wiring for and loose/ poor connections and
remake if necessary.
7. Inspect the condition of the condense trap for signs of debris
and possible blockage. If necessary remove the service plug, drain
and clean the compartment. Replace the plug, reassemble the
case and check for correct operation when the appliance is
running.
8. Check and clean the magnetic filter if it is of the serviceable
type, otherwise replace the cartridge. If it observed that there is
excessive amounts of corrosion product - black residue/sludge
check the inhibitor level in the system and top up with inhibitor
solution as required.
